Abstract

APERFEIÇOAMENTO TCP COM UTILIZAÇÃO DE CANAL LICENCIADO LIMITADA PARA REDES SEM FIO. Métodos, sistemas e dispositivos são descritos para a operação de um sistema de comunicações utilizando ambas as bandas de frequência licenciada e não licenciada. O espectro não licenciado pode ser utilizado como uma banda primária para transmissão de pacotes de dados através do espectro licenciado. A transmissão seletiva do subconjunto de pacotes de dados através do espectro licenciado pode ser baseada em um transmissor que falha em receber e uma mensagem de aviso de recebimento (ACK) em resposta a um ou mais dos pacotes de dados transmitidos no espectro não licenciado. A retransmissão seletiva pode ser baseada em um transmissor que detecta interferência e/ou pode ser baseado em um receptor que reporta informação sobre as condições de canal. Em alguns casos, um transmissor pode receber simultaneamente informação de condição de canal par a ambos o espectro licenciado e não licenciado. Em outros casos, o espectro não licenciado pode ser utilizado para transmissão de pacote de dados e espectro licenciado pode ser utilizado para mensagens ACK.TCP ENHANCEMENT WITH LIMITED LICENSED CHANNEL USE FOR WIRELESS NETWORKS. Methods, systems and devices are described for operating a communications system using both licensed and unlicensed frequency bands. The unlicensed spectrum can be used as a primary band for transmitting data packets over the licensed spectrum. The selective transmission of a subset of data packets across the licensed spectrum can be based on a sender failing to receive and acknowledgment of receipt (ACK) message in response to one or more of the data packets transmitted in the unlicensed spectrum. Selective retransmission can be based on a transmitter that detects interference and/or it can be based on a receiver that reports information about channel conditions. In some cases, a transmitter may simultaneously receive channel condition information for both licensed and unlicensed spectrum. In other cases, unlicensed spectrum can be used for data packet transmission and licensed spectrum can be used for ACK messages.
